Specification of Letters Patent.

Patented Mar. 16, 1920.

Application filed July 18, 1918. Serial No. 811,779.

. To all whom it may concern:

Be it known that I, Nroomnnns FRANCISCO REYNAL OCoNNoR, a citizen ofArgentina, and residing at Buenos Aires, Ar entina, have inventedcertain new and use Improvements in Medicine-Containers, of which thefollowing is a specification.

The present invention relates to medicine containers or capsules.

The principal ob'ects of the invention are to provide an article of thistype which when used may be automaticall filled with a predeterminedquantity of uid, and to provide a capsule which may be automaticallfilled without immersing the fingers or an instrument in the fluid.Other objects and features of novelty will be apparent from thedescription taken in connection with the drawings in which:

Figure 1 is a side elevation of a container constructed in accordancewith the resent invention showing the container w1th one end immersed ina fluid in the proper position for filling;

Fig. 2 is a sectional elevation of the container; and

Fig. 3 is an elevation of the container after it has been filled with afluid, certain portions being shown in section.

Referring to the drawings the container of the present inventioncomprises a sealed hollow shell 10, preferably of glass, from which theair has been exhausted. The exhausting of the'air and the sealing of thecapsule may be accomplished in any of the well known ways. The container10 is provided at one end with apart which is adapted to-be immersed ina fluid and then broken to provide a pin-hole opening through which theshell is filled with the fluid. Asshown, the shell 10 is tubular and hasthe extension 11 of gradually reduced diameter. At 12 this extension isbent back on itself thus forming a bight and a free arm 13. As clearlyshown in Fig. 2, the extension 11 is provided with a passageway which isin combination with the interior of the shell 10 and extends at least tothe bi ht 12. This passageway is of gradually reduced diameter so thatat the bight 12 a capillary tube is provided. The extension is weakenedat the bight so that when the arm 13 is moved laterally said arm willbreak oif at the bight, thus providing an inlet of very small diameterat the bight through which fluid may enter into the shell to fill thesame. As this inlet is of such small diameter the fluid will not leakout of the container. I

. The end ofthe shell 10 opposite the extension 11 is provided with ashort extension 14 formed with an interior passageway in communicationwith the interior of the shell 10, the upper end of Which'is sealed asat 15. When it is desired to withdraw the contents of the container theseal 15 is broken and a hypodermic syringe is connected to one of theextensions 11 or 14 to withdraw the fluid, air entering through theother extension.

In using the con tainer'of this invention the bi ht 12 is immersed inthe medicine with w ich it is desired to fill the container, it beingunderstood that the containers are made in different sizes to holdpredetermined quantities of medicine. Then the arm 13 is broken off :atthe bight 12 by grasping the tip of the arm and movin it away from thecontainer. The break w1l occur at the bight as this is the weakest partof the extension. Thereupon the fluid will rush through the small inlet,thus substantially filling the container 10. As the container is made tohold a predetermined quantity of medicine, this quantity will beautomatically measured out in the filling of the container. As the inletopeni is so very small, none of the medicine wil leak' out of thecontainer so that the container may be kept indefinitely or until themedicine is required for use. In order to withdraw the medicine from thecapsule the seal 15 is broken and then if the medicine is to be used ina hypodermic syringe said syringe is connected to one of the'extensions11 or 14 and the medicine withdrawn from the container, air enteringthrough the opposite extension.

Fromthe foregoing 1t is apparent that the container of this inventionprovides an exceedingly simple means for measuring out and storin aredetermined quantity of medicine. d urtl iermore, the container may befilled with medicine without the use of an instrument or immersing thefingers in 7 connected to the container and formed with a passagecommunicating with the interior of the container and extending at leastto the foot of the said leg, the curved section of said part beingweakened whereby the free leg may be broken off to open said passage,which is reduced to capillary size at the weakened portion.

2. An article of manufacture of the character described comprising atubular glass container from which the air has been ex-.

hausted having an extension of reduced diameter bent back on itselfforming a bight, said extension formed with a passage communicating withthe interior of the container, and being weakened at the bight, saidpassage being reduced to capillary size at the bight.

3. An article of manufacture of the character described comprising atubular glass container from which the air has been exhausted havingreduced hollow extensions at both ends, one extension having a tipadapted to be broken off and the other extension being bent back onitself forming a bight and being weakened at the bight.

In testimony whereof I afiix my signature.
